    I wonder to what extent this exists in other languages?

    The author of the linked article gives a nice neat (though perhaps not intentional) summary of why Java opts take on an almost "urban legend"-like status:

    First of all, microbenchmarks rarely measure what you think they're measuring. In the presence of dynamic compilation, you have no idea what bytecode the JVM decides to convert into native code or when, so you can't really compare apples to apples.

    In C, or just about any truly compiled language, you most certainly can measure the performance of two different ways of doing something.

    Then again, this counts as one of the many factors in the C-vs-Java wars... C programmers like determinism. Java programmers like idiot-proofness. If you need to factor in the amount of time it takes to unload the gun in "point at foot, pull trigger", you'll never really get a good idea of how long it takes to "shoot self in foot". ;-)

    The idea of "incorporation" exists as a convenient legal fiction for the sake of allowing the government OF THE PEOPLE to deal with a company.

    If that company has abused that legal fiction, not only not contributing to "the people" but actually depriving them of something they already had (in this case, variety in radio broadcasting), we not only have a right, but an obligation to terminate that company's existance.

    Or, to look at it another way, revocation of a corporate charter means essentially applying the death penalty to a company. Clearchannel "killed" radio, so should itself receive the death penalty as a punishment.


    But since when, in a free society, are people allowed to destroy someone's livelihood simply because they don't agree with it?

    Ever heard of payola? Y'know, that system of semi-legal extortion by which radio stations prevents artists without decently large budgets from getting radio play, thus effectively destroying their livelyhood because they don't agree to get down on their knees for the company?

    I understand XviD's implementation of MPEG-4 is based on H.263.

    XviD follows the MPEG-4 ASP (advanced simple profile) spec. Virtually all of the current major video codecs out there use some minor variant of this.

    H.264 usually refers to the MPEG-4 AVC (advanced video coding) profile. This promises a 2-4x size improvement at similar quality to the ASP. However, it has one major problem...


    So is anybody (including XviD) considering implementing it? I understand it isn't patent-encumbered. I could be wrong...

    Yes, an AVC implementation exists, but it provides its own demonstration of why no one uses it yet despite the improved size and/or quality... Namely, 30-45 seconds per frame at encode time. For a full-length movie, that comes out to two or three days for a single-pass encode.

    Additionally, even if you feel inclined to wait that long for the sake of quality (personally, I would), the link I gave above points to more of a proof of concept than a "real" viable codec. It needs quite a lot of tweaking just to make it compare to existing ASP codecs such as XviD.

    You haven't dealt with many "tech" managers, have you?

    In my entire career (roughly a decade doing primarily firmware engineering with an assortment of "normal" coding as well) , I have had exactly two managers with a clue.

    One I consider really decent, he knew what I did, and more importantly, he knew what he didn't know and wouldn't challenge me on decisions about things he didn't know.

    The other "knew C", and for the most part stayed out of my way and let me do my job. Incidentally, for any management-types reading this, you should aspire to meet this description - At least know the basics of what the people you "lead" do, and if you can't literally do their job for them, just leave them the hell alone. Give 'em a project and go back to your cube for a week.

    All the rest (I'd say over a dozen) believed that their pathetic little MBA meant they knew more about how to do my job than I did.

    Put simply, PHBs really do exist, and count as the majority (in my experience) of managers.

    Now, I don't mean to say they serve no purpose - I don't claim to understand the business world, so somebody better know "step 2" of code -> ??? -> profit. But when accountants give engineers crap about purely tech-oriented decisions, they need to ask themselves "do I want the job done, or do I want to prove my cluelessness to people who already consider me of dubious value to the ''team''?"


    Incidentally, regarding tech support, I have found it wanting for any real usefulness, other than a false sense of accountability for the PHBs. At my previous job, we had a rather large tech support contract with a company that provided a particular embedded OS to us, and when something went wrong, guess who ended up solving the problem? WE provided THEM more bugfixes than they provided us. No kidding or hyperbole involved here. They would always respond with "we'll look into it", and of course since we needed the code working "yesterday", we'd have to start working on their bugs on our own. On two occasions that I can remember, we had to send an engineer to their HQ to explain their own major architectural flaws to them so they wouldn't continue sending us "fixes" that re-broke what we'd already worked around.

    As an unsatisfied, irate, and now petulant, consumer, I find the RIAA reprehensible.

On the bright side, their legal fees on this one most likely exceed their gain, which means they've done nothing except further annoy their potential customers.

    As a member of a capitalistic economic system, I see the RIAA as subsidized obsolesence. If it insists on using an outdated business model to sell intangible "goods" based on artists of dubious skill, let it.

    A drug screen is meant to pick up illegal activity which poses a tangible safety and liability issue to a potential employer.

    Drug testing leaves open the possibility of false positives, yet that seems to matter little to those employers who use it. As the most trivial example, poppyseed bagels cause false positives for opiates (no, not just an urban legend).

    To address the "thought crimes" angle of your comment, though, many jobs now require applicants to take a simple "survey", which asks such questions as "do you consider it okay to steal from your employer". This expresses nothing but an opinion, yet if it the answer didn't matter, they wouldn't ask. So does having a self-serving personality, hating certain groups, generally exhibiting a "take advantage of anything within the letter of the law attitude" commit any crimes? Nope. But it may well keep some people from ever working again if a potential employer can automatically detect such personality traits.

    The problem under consideration here involves directly getting those answers from your brain. If they can ask survey questions such as I mentioned, why not make such a survey easier and less prone to people lying?

    Which gets back to the problem of "but only criminals will have to worry about the answers". If you think new tech will magically lack false positives, however, I have a bridge to sell you.

    And yes, just for clarification, I DO feel very strongly against drug testing, against personality testing, against "measurement" of any aspect of a potential employee not directly related to job performance. With drug testing, those of us actually having useful skills can send a message by letting such employers know exactly why we won't work for them after wasting their time through three rounds of interviews, forcing them to start over at great expense. With personality testing (at least in its current form), anyone but a complete moron can give the "right" answers. With completely passive raping of our brains for incriminating evidence that an employer might not like? No, that does NOT sound at all acceptible, and while not currently a privacy issue, most definitely a problem in the future.

    The problem with the 4GB limit (and under more realistic assumptions, 2GB) has little to do with the maximum memory a system can use.

    As a simple example of why this matters, let's say you have a system that needs tons of memory, like for rendering complex scenes or serving a huge database. Each process will want as much RAM as possible, but on IA32 (well, on any architecture, but the current problem only really applies to cheap-and-popular IA32), can only use up to the addressable limit.

    So you might think that you could use a machine with 64GB for a number of slightly smaller (but still memory-hungry) tasks. The flaw with that idea? Get real.
